Dallas, Text Application February 26, 1-949, Seria1"-No 7856 31- "icn ms- (01. 2. 0752)" This invention relates to machinesfor collating aipluralityl of "continuous paper webs in the production of manifoldwforms for anypurpose and it has particular reference; to such aczmachine marginal apertures 1 of v apaper: webg' to advance the latter through the machine. This advancing arrangement has been found to be the most practical; although it has "its disadvantages in that it;v limits the numbertof sheetshwhich can be accumulated on the studs of the-rollers, making it necessary to manually glue two .or-more runs of manifold sheets. when thelrequired'number of sheets in each manifold exceeds the'capacity of the machine for asinglerum- Thisccondition cannot be corrected bylengtheningfl-the studs of the rollers since they i would thenfail to register with the spaced perforations in the marginof the papertweband hence would-be ineffective to ads-n vance the latter-through the machine.

relationship. It will be observed that the meet-,

ing edges of the discs 22, which are adapted to cut the perforated margins from paper webs, are in horizontal alignment with the space between the assembling rollers 16 so that the assembled webs will move therebetween to be divested of the perforated margin. The form of web adapted to bev assembled by the machine is conventional and is identified in Figure 9 by reference numeral 23 whose margin 24 is provided with spaced perforations 25 and is separated from the web proper along the longitudinal line 26.

a At the front of the assembling machine is mounted a support 21 for a transverse shaft 28 on which is mounted a plate 29 and to this plate is secured-by means of bolts 33, a blade 3 I. When the shaft 28 is rotated, the blade 3| is brought into shearing relationship with a stationary, vertically disposed blade 32 (Fig. 8), mounted on a transverse bar 33 by bolts 34, hence the assembled webs, intheir passage between these blades will be severed into manifold units of predetermined length.

Each of the feeding rollers M, which are vertically spaced apart in the rear portion of the machine frame, are provided with circumferentially'spaced pins or studs 35 adjacent one end thereof. The assembling rollers l6 are also provided with like studs 36, correspondingly spaced and between each stud 35 is an opening 31. The studs on one roller l6 are staggered with respect to the studs on the companion roller in order that the studs on one roller will enter the holes 31 in the other roller, as exemplified in Figure 7. Hence, the apertures in the margins of the paper webs brought into assembly between the rollers will not escape engagement by the studs of each of the latter.

Situated rearwardly of the collating machine described above is a frame 38 (Figs. 1 and 3) between whose rear uprights 39' extends a series of vertically spaced shafts 40, each of which carries a pair of rollers 41 over which webs of paper, not shown, are adapted to pass as they are unrolled from rolls of paper mounted in a supply fame, not shown. Rearwardly of the uprights 39 is a single upright 42 from which rods 43 extend diagonally to one of the rear uprights 39 in vertically spaced relationship for guiding paper webs from rolls in a supply frame at right angles into the guide frame 38 in order that the webs may advance over rollers 4| and directly into the collating machine.

In its course through the guide frame 38, each paper web is constrained by a pivoted lug 44 (Fig. 'to engage an annularly grooved wheel 45 (Fig. 5) mounted on a shaft 43 and whose periphery is submerged in glue 4'! in a pot 48. This wheel distributes onto the web 23 two parallel lines of glue as shown at a in Figure 9, as the web is advanced thereover. The glue pots 48 are mounted on supports 49 which extend between the foremost uprights 53 of the frame 38.

To drive the described apparatus, an electric motor'5l is mounted on the front legs of the supporting frame H! which drives a belt 52, the latter, in' turn, driving a pulley 53, mounted on the shaft 28 which carries the shearing blade 23.

This same shaft carries a sprocket 54 which drives a sprocket 55 through chain 56. Sprocket 55 is mounted on a stub shaft 51 carried by an arm 58.

the latter, in turn, being slidably and swingably mounted on the shaft of the lowest of the assembling rollers l6 and held in adjusted positions by a pin 59 extending therethrough and into a, selected one of a group of holes 69 arcuately spaced in the side member [2 of the machine. By virtue of the adjustable arm 58, a change in the peripheral speed of the assembling rollers l6 and consequently the length of the manifold form may be made by substituting sprockets and gears of different diameters for the sprocket 55 and gear Bl which latter drives the lowest assembling rollerv l6 through gear 62, the adjustment of arm 58 compensating for the resultant difference in the length of the chain 56.

The stub shaft 51 carriesalso a gearfil which engagesand drives a large gear 62 mounted on the shaft of the lowest assembling roller [6,, as may be seen in Figure 1. A gear.63, mounted on the shaft of the upper roller [6 is engaged and driven by gear 62, thus the assembling rollers I5 are driven in opposite directions and at the same rate of speed.

To drive the upper series of the feeding rollers M, a chain 64 is passed over sprockets 65 mounted on the ends. of the shafts of these rollers and over a sprocket 66, mounted on the shaft of the lowest assembling roller l5.

On the opposite'side of the machine, a sprocket 6'! is mounted on the extended end of the shaft of the upper assembling roller [6 which carries a chain 68 engaging sprockets 69 on the shafts of the lower series of feeding rollers [4, thereby rotating these rollers in the same direction as the upper series.

Mounted also on the shaft 29 which carries the shearing knife 3| is a gear 10 (Figs. 1 and2). This gear meshes with a gear 'H- mounted on a shaft 12 therebelow and which shaft also carries a sprocket 13. A chain M engages this sprocket and drives a sprocket 15, mounted on a shaf-t15 extending between the foremost uprights 50 of the guide frame rearwardly of the assembling machine. A chain 11 having vertical leadsextends parallel with one of the uprights 50 (Fig. 1) and engages all of the several sprockets 18 mounted on the ends of shafts 45 carrying the glue 'distributing wheels 45, thereby rotating the latter in unison.

The shaft 16, driven by chain", also carries a pulley 19 which drives a belt 89 which in turn drives a' pulley 8! mounted on a shaft 82, journaled in bearings supported between uprights 39 of the guide frame 38. The shaft carries also a sprocket which drives a vertical lead chain 83 and which engages all of the sprockets 84 mounted on the vertically spaced shafts 40, thus to rotate the guide rollers 41 on these shafts.

Referring to Figure 2, the shaft 72 which is driven by enmeshed gears 10 and H on the opposite side of the assembling machine, carries a sprocket 85 which drives a chain 85, the latter, in turn, driving a sprocket on the shaft 2| which carries the lowest of the two cutting discs 22. The sprocket on shaft 2| is concealed in Figure 2 by a gear 81 also mounted on this shaft and which meshes with a gear 88 mounted-on the shaft 20 thereabove and which drives the uppermost disc 22 in unison'with the companion disc.

In Figure 11 is shown an exploded view of a ,paper web retaining assembly for each of the feeding rollers M; This assembly consists'ofa mounting 99 affixed to an upright I 3 of the machine frame and which supports a member 90 at right angles to a roller It. A coil spring 9| surrounds member 90 and is held under compression by a collar 92, the latter being secured in place on member 90 by a set screw 93. The collar 92 is slotted to receive an inwardly turned end 94 of a leaf spring 95, the latter having a slotted end 96 through which the studs 35 of rollers 14 pass when the spring 95 is tensionally held against the paper web as it passes over the roller to hold the same against displacement from the studs in event of too much play in the web between these rollers and the stock supporting rollers.

It is of particular importance to observe the relationship of the vertical series of minor or feeding rollers I4 in Figures 1 and 10 with a pair of major or assembling rollers I6, which relationship constitutes the novel characteristic of the invention over conventional collating machines.

It is of course obvious that while but four feeding rollers 14 are illustrated for convenience in illustrating, as many of such rollers may be incorporated as may be required to supply a complement of manifold forms. many as sixteen or eighteen forms are used. In conventional collators, this quantity of forms in a single manifold run would not be possible and it would be necessary to make two runs and manually glue the two together. In so producing the manifold forms the problem is encountered as to maintaining continuity in numbering since the form numbers are applied by the press which also prints and perforates the webs. When gluing by hand, many sets must be numbered also by hand,

which is not only time consuming but gives rise to error and further, this is considered waste of printed forms.

By arranging the feeding rolls l4 in vertical In some cases, as

alignment and locating these rollers in groups above and below the assembling rollers, a single Web may be passed across each feeding roller, thence betweeen the assembling rollers to avoid dislocating, the apertures in the webs in relation accumulation of paper on the latter.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
